Method and system for determining high precision geo-fencing using business property boundaries

A system for determining a geo-fence monitoring area for a business, the system comprising:

• a processing device;
• a database accessible by the processing device, the database storing property boundary data for properties, the property boundary data including parcel boundary definitions for the properties,
• wherein the processing device is configured to receive an address for the business, obtain rooftop coordinates for the business based on the received address, determine a parcel in which the business is located using the rooftop coordinates, obtain from the database property boundary data for the determined parcel in which the business is located, the property boundary data including a parcel boundary definition for property on which the business is located;
• determine a longest diagonal of a polygon formed by the parcel boundary definition for the property on which the business is located;
• create a circle, using the determined longest diagonal as a diameter, that is centered on the polygon formed by the parcel boundary definition;
• and
• register the circle as the geo-fence monitoring area for the business.
